Its sutle for some players, for me its become a problem as of late. They had one topic on the tech support for it and its closing soon.
Im curious, if noone else has experience the blur as you move accross the world. Many have called for many different fixes from tta to dlss disable to sharpening image and lock lower fps. I have tried a few but the blur is always there
Guys I can confirm that the best current fix, as guys have already mentioned here, is to get the latest nvngx_dlss.dll from techpowerup (NVIDIA DLSS DLL 3.1.13). Then just replace that file in your base Diablo 4 folder after each time you reload the Battle.net app / close the game (as it will revert it back to the 3.1.1 DLSS DLL version when you close the game or when you load up Battle.net - you will see the 33MB patch come through).
This doesn’t remove the blur completely, but it is now 90% gone. Much harder to notice while playing now … and especially in those slow camera pans during in game cutscenes.
I am running a 5950x, 3090 and the Alienware Ultrawide QD-OLED (so 0.1ms response times) … playing @ 3440x1440 with DLAA on.
Easiest way to test is to load into game as normal … then just zoom all the way in and look at your character standing still. You will see his/her helmet blur heavily when they are breathing looking at them from above.
Now log out … replace the DLSS DLL to 3.1.13 and watch your character breathing again. Blur will be almost gone now.
Just remember to replace the DLSS DLL everytime u load the game (after you open up Battle.net and just before you hit play) as it will revert back to the old 3.1.1 when you reload Battle.net / after you close the game.
Hopefully Blizz / Nvidia add the nvngx_dlss.dll at the driver level when the next driver comes out (like they have for other titles) … so it always uses the latest dll instead of the one that shipped with the game.
Wall of text … but it fixed it for me … try it for yourselves.
